FIRST AID MEASURES
Description
of first aid measures
General
advice Consult a physician. Show this
safety data sheet to the doctor in attendance.
If
inhaled If breathed in, move person into
fresh air. If not breathing, give artificial respiration. Consult a physician.
In
case of skin contact Wash off with soap and
plenty of water. Take victim immediately to hospital. Consult a physician.
In
case of eye contact Flush eyes with water
as a precaution.
If
swallowed Never give anything by mouth to
an unconscious person. Rinse mouth with water. Consult a physician.
Most
important symptoms and effects, both acute and delayed Central
nervous system depression
Indication
of any immediate medical attention and special treatment needed no
data available

FIREFIGHTING MEASURES
Extinguishing
media
Suitable
extinguishing media Use water spray,
alcohol-resistant foam, dry chemical or carbon dioxide.
Special
hazards arising from the substance or mixture Carbon
oxides, Hydrogen bromide gas, Sodium oxides, Mercury/mercury oxides.
Advice
for firefighters Wear self contained
breathing apparatus for fire fighting if necessary.
Further
information no data available
6.
ACCIDENTAL RELEASE MEASURES
Personal
precautions, protective equipment and emergency procedures Wear
respiratory protection. Avoid dust formation. Avoid breathing vapors, mist or
gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid
breathing dust.
Environmental
precautions Prevent further leakage or
spillage if safe to do so. Do not let product enter drains. Discharge into the
environment
must be avoided.
Methods
and materials for containment and cleaning up Pick
up and arrange disposal without creating dust. Sweep up and shovel. Keep in
suitable, closed containers for disposal.

HANDLING AND STORAGE
Precautions
for safe handling Avoid contact with skin
and eyes. Avoid formation of dust and aerosols.
Provide
appropriate exhaust ventilation at places where dust is formed.
Conditions
for safe storage, including any incompatibilities Store
in cool place. Keep container tightly closed in a dry and well-ventilated place.

EXPOSURE CONTROLS/PERSONAL PROTECTION
Control
parameters Components with workplace
control parameters
Exposure
controls
Appropriate
engineering controls Avoid contact with
skin, eyes and clothing. Wash hands before breaks and immediately after handling
the
product.
Personal
protective equipment
Eye/face
protection Face shield and safety glasses
Use equipment for eye protection tested and approved under
appropriate
government standards such as NIOSH (US) or EN 166(EU).
Skin
protection Handle with gloves. Gloves must
be inspected prior to use. Use proper glove removal technique
(without
touching glove's outer surface) to avoid skin contact with this product. Dispose
of
contaminated
gloves after use in accordance with applicable laws and good laboratory
practices.
Wash
and dry hands.
The
selected protective gloves have to satisfy the specifications of EU Directive
89/686/EEC and
the
standard EN 374 derived from it.
Body
Protection Complete suit protecting against
chemicals, The type of protective equipment must be selected
according
to the concentration and amount of the dangerous substance at the specific
workplace.
Respiratory
protection Where risk assessment shows
air-purifying respirators are appropriate use a full-face particle
respirator
type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to
engineering
controls.
If the respirator is the sole means of protection, use a full-face supplied air
respirator. Use
respirators
and components tested and approved under appropriate government standards such
as
NIOSH (US) or CEN (EU).
